FRANCIS SEYMOUR, OF PATERSON, NEW JERSEY.

MACHINE FOR SPINNING, DOUBLING, AND TWISTING FIBROUS MATERIALS.

SPECIFICATION forming" part of Letters Patent No. 253,431, dated February '7, 1882.

Application filed August 10, 1881. (No model.)

' of New Jersey, have invented certain new and useful Improvements in Machines for Spinning, Doubling, and Twisting Fibrous Materials, of which the following is a specification.

The objects of the invention are to improve the stop mechanism and to combine a spindle, pulleys, tube, rail, and oil-cup, as hereinafter described.

In the accompanying drawings, Figure 1 is a vertical transverse section of a machine embodying my improvements. Fig. 2 is a front elevation of a portion of the machine. Fig. 3 is a plan view of the stop mechanism. Fig. 4 is a plan view of the spindle, rails, and spinning mechanism. Fig. 5 is a vertical section of the spinning-tube, oil-cup, and rail of the first time-spindles. Fig. 6 is a like view of the tube, oil-cup, and rail of the windingspindle.

Similar letters of reference indicate corresponding parts. In the drawings, a a are the standards of the machine; I), the winding-spindle rail. 0 is the rail supporting the first time-spindles. d is a rail carrying the feed mechanism, and e is an upper rail carrying the fallers and other parts of the stop mechanism.

To the rail b, as seen in Fig. 6, is affixed a spindle, f, enlarged at f to fill the tube as far as the enlargement extends, and provided with a small spiral groove, whose capillary action assists in the rise of the oil.

Surrounding the spindle is the spinningtube, formed in two parts, h h, the upper part,

h, being cut away upon its lower extremity and having formed upon it the pulleys t z", and the lower part, h, surrounding the cut-away por-.

tion of the part h and provided near its upper end with an outer shoulder. Embracing the part It above the aforesaid shoulder, and held between said shoulder and pulley i, is a loose pulley, n. The bottom of the part h rests in an oil-cup, g, secured to rail b, and has formed in one side an opening for the admission of the oil between the spindle and tube.

The pulley i is connected by a belt with other pulleys formed upon the tubes of the first time-spindles, while the pulley t is driven by a belt from the driving-cylinder I, so that when the driving-cylinder revolves all the spindles are simultaneously operated.

The tube receives the spool, as shown, and is formed slightly tapering, so as to hold the spool tightly. A not or head on the upper end of the spindle f prevents the tube from rising. With this construction of spinningt-ube and spindle the spool is held firmly. there is no vibration or irregularity from the strain of the belts, and a high rate of speed can be safely used. The bearing-surfaces of the tube on the fixed spindle are kept thoroughly oiled by the oil'in the mp9, and to assist the capillary rise of the oil the enlarged portion f of the spindlef is formed, as shown, with a spiral groove.

0 is the traverse-rod, carrying a ring, 0, and traveler p, and fitted for movement by cam q and lever q. The cam g has bevel-teeth formed upon one of its sides, meshing with a pinion connected by a chain of mechanism with the bevel-pinion carried by the driving-shaft, as shown in Fig. 1.

The driving mechanism of tube h h consists of cylinder l and a loose pulley, 1, above the cylinder. cylinder and loose pulley in the manner shown, so as to extend in a nearly straight line to the pulley i of the tube. I MS a weighted shifting-lever connecting with belt k and sustained by the rod .9 from the stop mechanism.

The first time-spindles t and spinning-tubes u on rail 0 are similar to the spindles fj and tubes h h, except that each tube to has but a single pulley, u, around which the belt at from The belt 70 passes around both the pulley 6 passes. There are three tubes to, carrying spools, as shown.

The feed mechanism on rail d consists as follows:

a is a lever, carrying at one endtwo loose rollers, 11 b between which the twisted thread passes in a downward direction.

0 is a continuously-revolved roller, on which the roller I) rests normally, so as to be driven therefrom, and the. contact is maintained by the weight of rollers 11 b which over-balance the opposite end of lever (o The roller 0 has secured to one of its sides a bevel-pinion meshing with a second pinion borne by a horizontal shaft. The latter is connected by means of bevel-gearing with a vertical shaft driven ICO by means of bevel-gearing by the driving-shaft of the machine.

The stop mechanism is substantially similar to that shown in my former patent, No. 245,878, dated August 16, 1881.

d are the fallers, formed with eyes, through which the threads pass intermediately of the glass tubes 0 that sustain the threads.

f is a balanced lever, one end of which extends beneath the fallers, while the other end engages one end of a bent lever, 1 The lever connects to rod 8, that passes to the shiftinglever 1", before mentioned, and there is a lug, 71?, on lever that extends behind a similar lug, W, on the lever a of the feed-rollers.

k is a cam having continuous revolution imparted to it by a friction-wheel borne upon the same shaft and engaging with a like wheel borne by the shaft of the roller 0 It is so placedthat it strikes lever f when the latter is raised.

Z is,a latch placed to engage a pin on the bent lever y when such lever is moved by the cam. In case either thread breaks the downward movement of its faller depresses one end of leverf the other end rises into the path of cam W, the cam moves lever f endwise, and the lever 9 being thereby moved, rod 8 is drawn upward, and the shifting-lever 0' thereby operated and the belt is shifted to the loose pulley a. At the same time lug 7L2, acting on lug i swings lever a and raises the feed-roller b from roller 0 thus stopping the feed at the same time the spinning-tubes are stopped. The latch 1 looks the parts in this position. 011 return of lever g to its first position by hand the feed-rollers b I) carry lever 01. to its first position by gravity.

It will be seen that while the feed is arrested by the stop motion there is no positive connection between the stop mechanism and the lever carrying the feed-rollers. I thus avoid the necessity of accurate adjustment of the two motions which is required when the stop-motion lever, feed-roller lever, and shifting-lever are in connection positively, as shown in my before-mentioned application.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with fallers d lever f cam k roller 0 and mechanism for operating said cam and roller, of lever 9 provided with lug h and lever (0 provided with lug i and carrying rolls b b ,substantially as and for the purposes specified.

2. The combination of the spindle ff, the

pulleys i n, the tube h h, the rail 1), and the oil-cup g, substantially as shown and described.
